If your plant runs acetonitrile by the isotainer or railcar, we will beat your current program. RightPath Industries supplies acetonitrile (CAS 75-05-8) in high-purity/HPLC and technical grades, in isotainer and rail volumes down to drums and cases — with strong cost positions right now and same-day quotes.

Why do peptide manufacturers buy acetonitrile from RightPath?
Acetonitrile is the workhorse solvent of peptide manufacturing — the mobile phase for preparative HPLC purification and a core solvent across solid-phase peptide synthesis workflows. As peptide API demand has scaled, acetonitrile consumption per batch has scaled with it, and solvent cost has become a real line item in cost-of-goods. That is where we compete: aggressive pricing on both high-purity and technical grade, delivered in the format your plant actually consumes — isotainers, rail, tank trucks, totes, or drums.
What grades and volumes do you supply?
| Grades | High-purity / HPLC (gradient-suitable), ACS, LC/MS, technical/production grade |
| Bulk formats | ISO tank containers (isotainers), railcars, tank trucks |
| Packaged formats | 270-gal totes, 55-gal drums, 5-gal pails, 4x4L glass cases |
| Documentation | COA every lot, SDS, lot control, audit support |
| CAS / UN | 75-05-8 / UN1648, Class 3 |
Which acetonitrile grade does peptide work actually need?
Preparative and analytical HPLC steps need low-UV-cutoff high-purity acetonitrile; upstream washes, cleavage cocktails, and non-critical process steps often run fine on technical grade at a fraction of the cost. Most plants buy both — and save real money by not over-specifying the process-side volume. We stock both and will help you split the spec. See our guide to what HPLC grade acetonitrile means and acetonitrile safety and handling.
How does isotainer and rail supply work?
Isotainers (~6,000+ gallons) and railcars move your cost per pound well below packaged goods and cut container handling. We manage the hazmat logistics — UN1648 Class 3 — end to end, quote landed cost with freight included, and can structure standing programs with just-in-time releases so you hold less inventory on site.

Frequently asked questions
Can you beat our current acetonitrile contract?
Ask us to quote against it. We hold strong positions on acetonitrile right now in both technical and high-purity grades, and we price isotainer and rail volume aggressively. The comparison costs you one email.
Do you supply both HPLC and technical grade on one program?
Yes — split-grade programs are common for peptide plants: high-purity for chromatography, technical for process use, one supplier and one landed-cost structure.
What documentation comes with each shipment?
Certificate of analysis for the exact lot, SDS, and lot control on request — suitable for GMP-adjacent purchasing and audits.
What if we are not a peptide manufacturer?
The same acetonitrile programs serve HPLC labs, oligonucleotide manufacturers, electronics, and extraction — any operation consuming acetonitrile at volume.
